At $5,00 certainly good bang for your buck. Includes electric schematics as well as exploded parts view + parts list for reordering. Unfortunately no details on the PCB contents or working, but then again, this is not overly complex. Best bonus: this manual does contain the heavily searched for LED error codes as well as descriptions for test operation. Haven't gotten around to fixing the machine yet, one thing the manual won't do for you is getting it out of the kitchen assembly :-(
This was an excellent source of detailed assembly information on a device which is at least 12 years old. A very lucky find, coupled with great service.

4. Confirmation of the RF level
Test point: RF and VC (Vref) Test disc: TCD-782 Confirm that the RF waveform appears as shown below.
At 0.8 Vp-p or greater
VOLT/DIV: 200mV TIME/DIV: 0.5us
5. Confirmation of tracking balance
Test point: TE and VC (Vref) Test disc: TCD-782 Press the DSL button while the test disc is playing and confirm that the traverse waveform is as is shown below.
VC
VOLT/DIV: 200mv TIME/DIV: 2ms
6. Confirmation of each servo
It is possible to confirm the adjustment value of each servo by repeatedly pressing the MODE button while the test disc is playing. The switchover sequence is as stated below. Confirmation mode OFF -> Focus bias (FB) -> Tracking balance (TB) -> Tracking gain (TG) -> Tracking error offset (TEO) -> Focus gain (FG) -> Focus error offset (FEO) -> Confirmation mode OFF Example: Tracking error offset (TEO) Adjustment value-> 03
